(54) PRESSURE STABILIZER FOR PNEUMATIC ORGANIZER.

The invention relates to pneumatic arms and can be used in air spring rifles and pi: centuries. - i Known pressure stabilizers for air guns containing a box with an open movable cylinder, which is agitated in it. piston Eastwall. Under the action of gas overpressure, the pool moves in the barrel bore. The overpressure per bullet increases from zero when pool i HaxoflntEg ,. B of the breech, up to the maximal size, when the pool passes some distance in the bore. Next gfuzhina under: holds pressure on the bullet in the channel: la. On this principle, a spring for pneumatic rifle IZH-22, produced by Izhevsk Mechanical Plant, a PV rifle, developed by Izhevsk Machine Building Plant, was arranged. A similar principle of the action of foreign air rifles I, In these air rifles, the bullet movement begins when a slight boost pressure is reached. The initial part of the njTii in the bore until i reaches the maximum pressure. Schl. . -. sVi l, -. S; passes under less pressure, pressure; forcing changes depending on the size of the bullet, its weight significantly affects the accuracy of the rifle. These drawbacks - 1 cl are excluded in a rifle with a shut-off valve, nom, avt. № 152190 for cl. p41b 11 / oh from 1962 to create a constant new air pressure per bullet, in the first shot, in a large volume; I, I made a valve in the rod in the direction of the tube, the lever, the axle and the flange with gfu4 | zhina. Under the action of the spring, the rod covers the bore from the breech and separates the compressible volume from the breech of the bore. At the time of the shot ,. PRE; | Achieving a certain pressure, the piston turns on the axis, which is the second: | shoulder shifts the rod, opening the channel: the barrel. Compressed air under constant pressure “singing while shooting” acts on the bullet. The statement of the specified cut-off clap; Pan greatly complicates the design of the switch;

In the stalled backrest 1, the ferrule 2 with the barrel 3 is pressed, which is held by the pulley 4. The breech 5 of the barrel protrudes into the compressible volume formed by the pori; 7, moving under the action of the spring 8 in the cylinder 9, is made on the breech Exit 10, which is a tray DL51 of the bullet stopping point 11 into the barrel bore. Keinal CTBOjia from the breech is closed with a pin 12 with an emphasis 13. On the continuation of the breech bore, an index valve 14 is spaced out, preventing (up to a maximum pressure of Ji-compressible volume) reaching the barrel bore and on the bullet, Cylindrical. A flap valve is pressed against the abutment by a spring 15, which rests at one end against the protrusion 16 on the valve and with the other end at the nest 17 on the holder; The receiver box is made a window 18 against removal on the barrel for postavki kana, l barrel. The barrel in the holder sdnn T to the window by the amount Q. for ease of bullet insertion into the bore. The protrusion is made on the piston.

The position of the parts, when the piston 7 moves to the forward position under the action of the squad 8, is shown in FIG. 1, In this; .1 position window 18 on the receiver 1 by cylinder 9, valve 14 is pressed 13 against stop 13 and, closing the opening 10, separates the bore of the barrel 3 with a pool of 11 rrr compressible volume. The overpressure of iTymo 11 equals well,

When the piston 7 approaches the valve 14 (Fig. 2), the pressure in the compressible volume 6 approaches the maximum. Continuing the movement, the piston moves the protrusion 19 to the valve 14 and releases the aperture 10 from the valve shutdown, the compressible volume 6 to the canal / valve satzrla i 3. The pressure of the gun to the bullet 11 is maintained by the spring 8 over the entire length of the bore.

To place an alternate bullet into the bore (Fig. 3), it is necessary to move the piston 7 with the slide 9 to the rear position, while the piston 7 compresses the spring 8. In the rear position the piston 7 is held by a sprint mechanism. The valve 14 under the action of the spring a1 15 presses against the stop 13 closing 10. I act with my thumb and pointing finger, which holds the pool D, onto the valve 14, is released from the outlet 10 and the next pool is inserted into the channel STEOL. After the bullet has been set, the valve 14, under the action of the spring 15, overlaps the recess 10 and presses against the stop 13. Before the shot, the peel 9 must be shifted to the forward position and forward

; cover window 18 on the receiver 1; For the firing of the piston 7, the piston 7 is released from the trigger mechanism. Under the action of the spring 8, the piston is moved to the front position and the gas is compressed in volume 6. Then the cycle is repeated.
